Granted: 1991-12-10
Abstract: ABSTRACT OF THE DISCLOSURE           A  process  is  disclosed  for  producing  high brightness kaolin from ore containing silica, other types of clays, minerals such as ilmenite micas, feldspars and various metal  silicates  as  well  as  organic  matter.  The  process consists  of  sizing,  a  double  floatation  step,  magnetic separation, leaching and oxidative brightening steps. This is a novel combination of conventional unit operations and in particular the use of a double  floatation step to remove quartz  and  various  trace  minerals  that  interfere  with achieving high optical brightness for kaolin.

Granted: 1993-03-30
Abstract: ABSTRACT REMOVAL OF CATALYST REMNANTS FROM POLYMERS           A new process for removing palladium catalyst remnants from copolymers of carbon monoxide and olefinically unsaturated compounds is disclosed.  The process comprises contacting the copolymers with a complexing agent for palladium at a temperature of at least 10°C higher than the temperature at which copolymerization has been effected.  Removing at least part of the catalyst remnants improves the overall process economy and increases the stability of the resulting polymers when processed in the molten state, substantially reducing their discolouration, decomposition and gelling.

Abstract: Abstract The  invention  relates  to  a procedure for measuring the rate of penetration VF  of  a  drill  bit  fixed  to the lower end of a drill string lowered into a well.    During  an  initial  period,  the  well  is  drilled  keeping,  on average,  the  value  of  weight F of the drill string measured at the surface  relatively  constant,  and  the momentary values of the drill string  rate  of penetration VS and the weight F are measured at the surface  at  different  successive  moments.    The value of the drill string  average  rate  of penetration VSM at the surface is determined from the  values  of  VS  measured and the successive values of dF/dt of  the  first  derivative with  respect  to time. The coefficient of apparent  rigidity  of  the  drill string during the initial period is then  determined  from  the values  of  VSM,  VS and dF/dt.  Finally, the rate VF is calculated.

Abstract: An apparatus and/or method utilizing a computer, for creating a relational database, the relational database contains a plurality of relations and each of the relations contains one or more columns and rows. A column has one or more values, which all have a common characteristic. Each value of the column corresponds to one of the rows of the relation. Each row contain some or more values in each value is from a different column. The values in each row have one or more characteristics. The creation of a relational database occurs in three steps. First, for each characteristic of the relational database, a set containing a plurality of unique values is formed. Second, for each relation of the relational database, one or more subsets of each set containing unique values of the relation is formed. Each of the subsets contains one or more of the unique values of one of the sets. Third, the relations of the relational database are formed. More particularly, for each subset associated with a particular relation, one of the columns of the relation is formed. Each column contains one or more of each unique value in the subset, and each unique value of the column occurs in one or more rows of the relation.

Abstract: Disclosed  is  an  improved  apparatus  and method  for  collecting,  freezing  and  removing  a liquid  such  as  blood  or blood  components,  and particularly blood plasma.  In accordance with the present  invention,  a  container  (16)  for  blood plasma is defined by a pair of substantially flat, flexible  opposing  sidewalls  (40,  42)  which  are substantially adjacent when the container is empty. The sidewalls are peripherally sealed together to define an interior compartment, and the side seals (44,  46)  converge  toward  one end  (48)  of  the container.  After a selected quantity of plasma is collected in the container, the filled container is formed and frozen in a wedge-shaped configuration, with  the  opposed  sidewalls  (40,42)    converging toward the end of the container.  An air space (82) may be provided in the top of the container so that a knife (86) may be easily inserted into the frozen container without contacting the frozen liquid (88) therein.    Slight warming  of the container then permits  the  frozen  contents  to  be  removed efficiently as a single slug.  Also disclosed is a form  (60)  for shaping  a container as described above into a wedge-shape for freezing.   The form includes a pair of rigid, perforated walls (62, 66) hinged together at one end (64) and configured to receive a container therebetween.  The rigid walls of the form are disposed to shape the container walls  into  a  converging  configuration  during freezing.

Abstract: ABSTRACT         Methods and apparatus for vane segment alignment and support in a combustion turbine.  The vane segment alignment device is comprised of a rotatable, eccentric bushing and pin which is inserted into a slot of the vane segment.  The eccentric bushing is further comprised of a cover plate which is peened to a splined torque plate thus holding the eccentric bushing is place against the vane segment but allowing for fine adjustments of the alignment of the vane segments. The vane segment support and alignment device provides for efficient and economical adjustment of the vane segments especially in electric generating plants where combustion turbines undergo high peak load operation.  Additionally, the vane segment support and alignment device transfers torques and moments generated by aerodynamic flow from the vane segments to an inner cylinder thereby reducing the amount of misalignment due to aerodynamic drag.
